Specification of Letters Patent.

Patented. Feb. 19,1907.

Application filed August 16,1905. Renewed November 2, 1906. Serial No.341,781.

To all whom it may concern: 1

Be it known that I, GEORGE SAGUE, a citizen of the United States, and aresident of Poughkeepsie, in the county of Dutchess and State of NewYork, have invented certain new and useful Improvements in Machines forCleaning or Treating Printers Rollers, of

machine which will with certainty and rapidity efficiently remove theaccumulation of ink, paper fiber, and other matter from printers rollerswithout injury to the surfaces of the latter.

In the preferred construction the machine of my invention will-comprisetwo pairs of conveying-rollers mounted in end-to-end relation uponparallel shafts and separated from each other at their adjoining ends bya suitable space, Within Which is mounted an oblique scraper-blade, overand in contact with which the roller to be treated, while being rotated,is carried by the aforesaid pairs of rollers. The conveying-rollersrotate and are rigid on their shafts, and said shafts have alternatelimited reciprocatory motions imparted to them, one of said shafts, withits end-to-end rollers thereon, moving forwardly, while the other shaft,with its end-to-end rollers thereon, is moving backwardly, these shaftshaving a constant reverse reciprocatory motion. The conyeying-rollerssupport the printers roller to be treated and, due to their reversereciprocatory movements, propel the printers roller along over thescraper-blade, while at the same time the printers roller has a rotarymotion imparted to it, due to the rotation of the conveying-rollers uponwhich the printers roller rests, the oonveying-rollers beingsufficiently separated to support the printers roller upon and betweenthem. The conveying-rollers are of special character, in that onelongitudinal half of each of said rollers is grooved longitudinally andthe other longitudinal half thereof is grooved circumferentially, andthe end-to-end rollers at one side of the machine are so set withrespect to the end-to-end rollers at the other side of the machine thatwhen the rollers at one side of the machine are moving forwardly theircircumferential grooves will be in engagement with and propel theprinters roller forwardly, while the rollers at the other side of themachine and moving backwardly will have their longitudinal grooves incontact with the printers roller, said longitudinal grooves permittingsaid last-mentioned rollers to slide backwardly without injury to theprinters roller and also facilitating the rotation of the printersroller. The conveying-rollers at one side of the machinewhen moving forwardly thus propel the printers roller forwardly, and when theconveying-rollers at the other side of the machine move forwardly theypropel the printers roller forwardly with them, and thus the printersroller while rotating is propelled forwardly first by the rollers at oneside of the machine and then by the rollers at the other side of themachine, this alternate action being continuous and the movement of theprinters roller being gradual, due to the fact that theconveying-rollers are only permitted to have a short throw.

The grooves on the conveying-rollers are not only beneficial, in thatthey pro el the printers roller forwardly against the scrap erblade whenthe latter is em; .loyed, and finally convey the same from the machine,but those rollers at the receiving end of the machine also serve toconvey the solvent to the printers roller and knead or -massage andthoroughly scrub the surfaces of said roller, so that by the time theprinters roller has reached the scraper-blade the foreign matter on saidroller will have become so thoroughly dissolved and removed that theduty of the said blade will be to aid in drying or removing the solventfrom the printers roller as the latter moves over it.

The rollers at the delivery end of the machine are of the sameconstruction as the rollers at the receiving end of the machine; butsaid rollers at the delivery end of the machine do not run in a solventand are utilized in carrying onward and rotating the printers roller andin imparting a final cleansing and finish to the same,in that saidrollers, due to their rapid rotation and reciprocation and the frictionthey generate against the printers sition upon the conveying-rollers.

roller, vaporize any solvent remaining on the same. I prefer to apply asmall quantity of water to the inner end portions of the rollers at thedelivery end of the machine, so that they may perform what is, ineffect, a sponging operation on the printers roller, and finally dry offthe same before it leaves the machine, this sponging and dryingimparting a finish to the surface of the printers roller. The quantityof water applied to the deliveryrollers should be very small and justenough to swell the surface of the irinters roller and make it slightlytacky and scatter any kerosene that may have adhered to it.

The main novel part of my invention resides in the rotary reversereciprocatory rollers to receive on and between them the printers rollerand having on opposite parts differential friction-surfaces adapted torotate, scrub, and propel said roller, the first or receiving pair ofsaid rollers running in a solvent of printers ink and scrubbing the inkfrom the printers roller and the final or delivery pair of said rollersfinishing and discharging said roller from the machine.

I do not limit my invention to all of the features hereinbefore referredto as embodied in the preferred construction, as will appear Ihereinafter.

Referring to the drawings, Figure 1 is a top view, partly broken awayand partly in section, of a machine constructed in accord ance with andembodying the invention. Fig. 2 is a front side elevation, partly brokenaway, of same. Fig. 3 is an end view of same, taken from the right-handend of Figs. 1 and 2 and showing a printers, roller in po- Fig. 4 is avertical transverse section of same on the dotted line 4 4 of Fig.2.Fig. 5 is a detached top view, partly broken away, of the two pairs ofconveying-rollers and their shafts and drivinggears, this figure ascompared with Fig. 1 showing the left-hand rollers as moving backwardlyand the right-hand rollers as moving forwardly, the receiving or powerend of the machine being considered the front end thereof. Fig. 6 is avertical transverse section through the machine, taken on the dotted.lines 6 6 of Figs. 2, 5, 7, and 8 and by dotted lines shows a printersroller in position upon the conveying-rollers with the latter in therelation in which they are shown in Fig. 5. Fig. 7 is an elevation,partly broken away, of the rear side of the machine with a portion ofthe latter in section on the dotted lines 7 7 of Figs. 4 and 6. Fig. 8is a detached to view, partly broken away, of a portion of tie machine,taken on the dotted line 8 8 of Fig. 6 and showing more especially asupplemental tank secured below the main frame and containing tworollers, one

. for supplying water to thedelivery conveying-rollers and the otherserving to cleanse said rollers. Fig. 9 is an enlarged detached top viewof the frame which carries the oblique scraper-blade and the guide whichdirects the end of the printers roller thereto. Fig. 10 is an end viewof'same looking at the lower end of Fig. 9. Fig. 11 is a side elevationof same, taken from the right-hand side of Fig. 9 and Fig. 12 is adetached face view of the scraper-blade, taken in thedirection of thearrow 12 in Fig. 9.

The general frame of the machine comprises an elongated rece tacle 20,supported at its ends by suitable en frames 21 22, which are below thereceptacle connected by a rod 23. The receptacle 20 isdivided by atransverse partition 24 into .two compartments 25 26, Fig. 1, the formerof which constitutes a tank to receive the kerosene or other solventwhich may be used to soften the foreign matter on the printers rollers.At its inner end the compartment or tank 25 has a deep section 27, Fig.2, into which the foreign matter scraped from the printers rollers maygather and which is provided with a discharge-orifice 28, adapted to beclosed by a plug 29.

Mounted in suitable bearings in the upper edges of the partition 24 andthe ends of the receptacle 20 are the parallel. longitudinal shafts 3O31, which project outwardly beyond the front end of the machine and havesecured upon them the oblique or wabble gearwheels 32 33,, in meshwith abroad driving gear-wheel 34, which is driven by ower from a belt-wheel35. The gear-whee s 32 33 are each at one edge confined between a pairof fixed jaws 36, supplied with rollers or trundlewheels 37 to engagethe side surfaces of said gear-wheels, whereby during the rotation ofsaid wheels to rotate the shafts 31 they are compelled to have amovement forwardly and backwardly on the broad gear-wheel 34, and thismovement I utilize for thepurp ose of securing reverse forwardly andbackwardly sliding movements of the shafts 3O 31 in their bearings, oneshaft moving forwardly while the other shaft moves backwardly and thisreverse alternating sliding movement of said shafts being continuouswhile the driving gear-wheel 34 is in motion.

The shafts 30 31 are for convenience connected at their endsand'adjacent to the partition 24 by links 38, which when the bearingcap39, Fig. 1, is removed from over the shaft 31 permit the shaft 31 to beturned on the arc of a circle upwardly from the receptacle 20, thusexposing the interior of the latter and allowing the parts of themachine to be conveniently cleaned. The bearings for the shaft 30 havebearing-caps 40; but it is unnecessary to provide more than one bearingof the shaft 31 with a cap 39..

IIO

Upon the shafts 3O 31are respectively se- Figs. 3, 4, 6, placed uponthem. The rollers 41 43 constitute a pair of receiving-rollers at thefront end of the machine, because the printers roller to be treated isfirst placed upon them, and the rollers 42 44 may be re garded asconstituting a pair of deliveryrollers, since they receive the printersroller from the rollers 41 43 and propel it forwardly until an attendantmust support its forward end and finally lift it from the machine. Therollers 41 42 43 44 are preferably hollow and made of brass, and theyare rigidly fastened upon the shafts 3O 31, so that the latter mayimpart their movements, hereinafter described, to said rollers.

The rollers 41 42 43 44 are all alike in construction, and each isformed in about one longitudinal half of its surface with the series ofparallel longitudinal grooves 46 and in the other longitudinal half ofits surface with the series of parallel transverse or circumferentialgrooves 47, which preferably are eccentric in outline, as indicated inFig. 6, said grooves 47 being deeper at their center and thencediminishingtoward their ends, which merge into the general surface ofthe rollers adjacent to the outer longitudinal grooves 46. The rollers41 42 are so set on their shaft 30 with relation to each other and tothe rollers 43 44 on their shaft 31 that the transverse grooves 47 ofthe forwardly-moving rollers and the longitudinal grooves 46 of thebackwardly-moving rollers will always in that relation engage theprinters roller, said transverse grooves propelling the printers rollerforwardly and said longitudinal grooves slipping backwardly against theforwardlymoving printers roller without injury to the same, asrepresented in Figs. 5 and 6, in which the rollers 41 42 are shown ashaving completed about one-half of their forward stroke and the rollers43 44 as having completed about one-half of their backward stroke. Theshafts 3O 31 rotate in the same direction while performing theiralternate reverse reciprocating movements, and hence when the rollers 4142 reach the end of their forward stroke their transverse grooves 47'roller, and their transverse grooves 47 will pass into engagement withsaid roller, whereby on the succeeding forward stroke of said rollers 4344 they, with their transverse grooves 47,

will be enabled to engage and move the printers roller forwardly. Thuswhen the rollers 41 42 move forwardly their transverse grooves 47 engagethe printers roller and convey it forwardly, and at the same time therollers 43 44, with their longitudinal grooves 46 in contact with saidroller, move backwardly, and when the rollers 43 44 move forwardly theirtransverse grooves 47 engage the printers roller and convey itforwardly, while at the same time the rollers 41 42, with theirlongitudinal grooves 46 in contact with said roller, move backwardly. InFig. 1 the rollers 41 42 are shown as having reached the end of theirback stroke and with the transverse grooves 47 thereof turning upwardlyto engage the printers roller, while the rollers 43 44 are representedas having reached the end of their forward stroke, with their grooves 47leaving the printers roller and their longitudinal grooves 46 turningupwardly to engage said roller.

The transverse grooves 47 at their edges form walls which engage theyielding surface of the printers roller, and hence with each forwardthrust of the conveying-rollers, which only takes place when saidgrooves are up and in engagement with the printers-roller, the latterroller is moved forwardly or carried bodily forward with theconveying-rollers then moving forwardly. The longitudinal grooves 46also at their edges form walls which engage the yielding surface of theprinters roller, and since this engagement is along longitudinal linessaid walls may slide or slip longitudinally along the printers roller;but, due to the fact that at the same time the backwardly-moving rollerscarrying said. walls are rotating, said walls by their engagement withthe printers-roller assure the due and proper rotation of the same whilesaid roller is being propelled forwardly by the transverse grooves 47 ofthe forwardly-moving conveying-rollers.

All of the surfaces of the rollers 41 43 42 44 aid in the rotation ofthe printers roller; but

this rotation is facilitated and assured by the presence of the grooves46, which also facilitate the backward movement of the conveying-rollerswithout injury to the printers rollerj The transverse grooves 47 arepreferably given an eccentric outline, so that they may not have a harshaction either on engaging or leaving the printers roller.

The rollers 41 43 and 42 44 very rapidly scrub the surface of theprinters roller, as well as rotate and propel it, one main purpose ofrotating the printers roller being that the said rollers may scrub itsentire surface. The rollers 41 43 run in solvent, and hence theirscrubbing action effects the softening and. removal of the ink and otherforeign matter from the printers roller. The rollers 41 43 and 42 44being formed on opposite parts with the grooves 46 47 presentdifferential frictional surfaces to the printers roller, and therebysaid roller while being scrubbed is propelled from the machine. Duringthe forward thrusts of the rollers 41 43 and 42 44 there is always aslippage between them and the printers roller, due to the softer natureof the latter and the presence (at the receiving end of the machine) ofink and solvent thereon, and this slippage is beneficial in that a partof the scrubbing of the the printers roller, said matter falling intothe deep section 27 of the tank 25. The blade 48 is fastened by screwsto an oblique arm 49, forming a part of a general supporting-frame 50,Figs. 9, 10, 11, pivotally hung upon the shaft 30 and having a weightedend 51, whose tendency is to yieldingly move the blade 48 upwardlyagainst the printers roller. The edge of the blade 48'describes the arcof a circle greater in diameter than the diameter of printers rollers,and hence the blade 48 may not only efliciently engage the entiresurface of a printers roller without injury to the same, but is adaptedto all the varying diameters of printers rollers. I also provide theframe 50. with an inclined shoe 52, upon which the end of the pi intersroller, propelled bythe rollers 41 43, will first pass, and therebydepress the blade 48 sufficiently for the latter to avoid being struckon its face by the blunt end of the printers roller and to make itsengagement with the circumferential surface only of the printers roller.The frame 50 is also provided with an arm 53, which extends below theshaft 31, Fig. 1, and is connected with a spring 54, which aids theweight 51 in keeping the scraper-blade 48 yieldingly pressed upwardlyagainst the printers roller. The location of the end of the arm 53 belowthe shaftv 31 enables the latter to act as a stop for preventing thescraper-blade from ever being turned upwardly to an undue extent.

At the delivery end of the machine I provide a pair of smooth-surfacedwheels 55, Figs. 1 and 2, to receive the advancing portion of theprinters rollers as the same are propelled onwardly from the machineby-the rollers 42 44. The opposite sides of the tank 25 may be providedwith upwardly-extended plates 56 to prevent any kerosene or othersolvent from being splashed over said sides during the use of themachine.

Below the compartment 26 of the main receptacle 20 is secured a casing57, Figs. 2, 6, 7, and8, which contains at opposite sides of a partition58 the rollers 59 60, the former of which is a rubber-covered roller forfeeding a limited quantity of water from the waterchamber 61, Fig. 7, tothe roller 42, while the roller 60 is covered with the same kind ofcomposition as that used in making printers rollers, and its purpose isto aid in cleaning the rollers 42 44 in the manner hereinafterdescribed. The rollers 59 60 are mounted on the same shaft, andsaid'shaft may have a limited sliding movement in its bearings, thisbeing to enable the rollers 59 60 to move back and forth with the roller42, with which they are in contact and from which they derive theirrotary movement." Each roller 59 60 is provided with a scraper 62, whichmay be adjusted by screws 63.

In the employment of the machine kerosene or other suitable solvent willbe poured into the tank 25 and water into the waterchamber 61. Thekerosene in the tank 25 should cover about one-third of the rollers 4143. Upon power being applied to the beltwheel 35 the shafts 30 31 andpairs of rollers 41 43 and 42 44 will be given their rotary andalternate reverse reciprocatory movements, and thereupon the printersroller will be placed lengthwise upon and between the rollers 41 43,which due to their movements and grooves 46 47 will both rotate andpropel the same and feed the solvent up to and against every part ofsaid roller. The grooved rollers 41 43 not only rotate, propel, anddeliver the solvent to the printers roller,

but knead up or massage its surface, whereby a the solvent is enabled toact quickly and thoroughly and said rollers are enabled to efficientlyscrub the ink therefrom and the surface of the roller is prepared forthe action of the scraper-blade. The movement of the rollers 41 43propels the printers roller endwise across the scraper-blade 48 and ontothe rollers 42 44,which then coast with the rollers 41 43 in moving theprinters roller onwardly. The printers roller while traversing thescraper-blade 48 has the greater portion of the solvent and anyremaining foreign matter scraped from its surface. The rollers 42 44 aidin moving the printers roller over the scraper-blade 48, and they imparta final or finishing treatment to said roller. tions the rollers 42 44by their movements deliver the printers roller in a dry condition fromthe machine. When a limited quantity of water or other suitable liquidis delivered to the roller 42 by the roller 59, this liquid will bedistributed over the printers roller and scatter any kerosene that mayhave been carried on said roller beyond the scraper-blade 48. The wateralso lubricates the rollers 42 44 and facilitates the travel of therinters roller u on the same and it also l/Vithout regard to otherconsidera- I portions of the roller 42. .The composition roller 60 isprovided to exhaust from the rollers 42 44 any coloring-matter that maybe carried to them by the end or other part of the printers roller. Anysuch coloringmatter will be distributed on the rollers 42 44 andprinters roller and will exhaust onto the roller 60. The rollers 42 44aid in conveying the printers roller through the machine, and they maybe used for sponging and drying and giving a finish to said roller. Irecommend the employment of the rollers 42 44, but do not wish to limitmy invention in every instance to such rollers, since the rollers 41 43apply the solvent and propel the printers roller across the obliquescraperblade and means other than the rollers 42 44 might be adopted toreceive the printers roller as it passes said blade.

In its preferred embodiment my invention consists in a machine havingthe two pairs of conveying-rollers 41 43 and 42 44, provided overone-half of their surfaces with longitudinal grooves 46 and over theother half of their surfaces with transverse grooves 47, and an obliquescraperblade 48, interposed between the ends of said pairs of rollers,so that the latter may while supporting and rotating the printers rollermove the same across said blade for effecting the cleansing of the same,said rollers 41 42 and 43 44 at opposite sides of the machine havingalternate reverse short reciprocatory move ments and all rotating in thesame direction. I do not desire to limit my invention to any specialmethod of applying the solvent to the rollers 41 43 and printers rollerunder treatment; but for the sake of economy and the attainment of thehighest efficiency I prefer to fill the tank 25 With the solvent untilabout one-third of the rollers 41 43 are covered thereby, under whichcondition the rollers 41 43 when in rotation may become flooded with thesolvent.

While I have hereinbefore described the preferred embodiment of myinvention, especially for rapidly cleaning typographic rollers andimparting a final finish to the same, I desire it understood that all ofthe'features hereinbefore described are not absolutely essential to asuccessful use of the machine. In many instances the rollers 41 43 bytheir rapid rotation, their length, their peculiar and effectivetreatment of the surface of the printers roller, their kneading andattrition of same, and their flooding of the same with the solventefficiently remove the ink and foreign matter from the printers rollerbe fore the surfaces of the latter reach the scraper-blade 4S, and inthese instances the duty performed by the said blade is mainly one ofremoving from the printers roller the solvent which has been carriedthereby beyond the rollers 41 43. The blade 48 does effectively and veryrapidly remove the solvent from the printers roller and in large measuredries the printers roller; but since in the instances referred to therollers 41'43 remove the accumulated foreign matter from the printersroller I do not'wish to limit this part of my invention to the use ofthe scraper 48, since under such conditions the drying of the printersroller or the removal of the solvent therefrom may be accomplished bymeans other than said scraper, the adhering accumulated foreign matteron the printers roller having already been removed and it only remainingto clean the solvent from the printers roller, which may be done bysponging or otherwise. In instances in which it may not be necessary toemploy a scraper 48 in conjunction with the rollers 41 43 I prefer toeffect the removal of the solvent from the printers roller and thesponging and final finishing of the same by means of the rollers 42 44,which do not run in solvent and which by their kneading and attrition ofthe roller will remove the solvent therefrom and finally deliver theroller in a dry finished condition. As hereinbefore described, I apply alimited quantity of Water or other sponging liquid to the roller 42, soas to scatter any kerosene on the printers roller and sponge the same,and I also apply to said roller 42 an exhaustingroller 60. In additionsponges may be applied to or held against the rollers 42 44 during theiroperation to further exhaust allsolvent therefrom and keep them clean.The rollers 41 43 and 42 44 may thus constitute the main features of themachine, since in many instances they are entirely efficient inthoroughly cleansing and finishing the printers roller without the aidof the scraper 48.

In the treatment of lithographic rollers the conveying-rollers 41 42 4344 may not possess the longitudinal grooves 46 and trans verse grooves47, but may be left plain where the longitudinal grooves are shown andmay be rough or have sandpaper applied to them where the transversegrooves 47 are shown, under which conditions the plain longitudinalsurfaces of the conveying-rollers may slip backwardly along thelithographic roller and the rough or sandpa er transverse surfaces ofthe conveying-r0 ers will propel the lithographic roller onwardly and inaddition impart a desirable surface or graining to the same. Myinvention is not therefore confined in every instance toconveying-rollers which possess transverse'grooves 47 and longitudinalgrooves 46, but comprises more generically conveying-rollers which haveon one part of their circumferences transverse surfaces adapted toengage and longitudinally propel the printers roller and on another partof their circumferences longitudinal surfaces adapted to slip backwardlongitudinally against said roller, with means for rotating theconveying-rollers and imparting to them alternate reverse reciprocatorymotions.
